Harry calls Fireworks AI the best inference product. Ev sees both as top three market leaders alongside Baseten.
"Lin and the team at Fireworks AI by far I think have the best inference product."
Compared to Baseten and Modal
"What has Modal done then that Baseten and Fireworks AI haven't to build that?"
Competitor to Modal
"Like we have Fireworks AI, we have Baseten, we have Modal... they really are like the three champions of the market and I think we're going to see more consolidation to those three than less."
Alongside Baseten and Modal
"My firm Atreides led the last Fireworks AI round and it was actually hard to price it because they were growing so fast."
Listed with Baseten, Together, Modal, and Cognition as open-weight-first companies
"I'm an investor in Fireworks, as is Sequoia. And I think the biggest concern I would have as a Fireworks or a Baseten or a Modal investor is that big enterprises are concerned about Chinese models."

"Open source getting closer to the frontier and companies like Fireworks making it really easy to customize a model such that you can get in some cases better than frontier performance for meaningfully lower cost — that is a godsend for t..."
Compared to using frontier models alone; enables hybrid routing between custom RL models and frontier models like Claude
"if you run this on fireworks AI, it's about 1/8 the cost of running the cloud API or the open AI API"
Significantly cheaper than Claude and OpenAI APIs
CoreWeave
Direct rival
GPU cloud compute provider
Jerry says Fireworks wins because its team deeply understands PyTorch and will do more fine-tuning and customization than rivals like CoreWeave.

"I'm lucky I invest in Fireworks versus Base 10 or CoreWeave or any of the other inference providers. Why? Because that team was the geniuses that understood Python the best — PyTorch in particular. They're going to move up the stack, do ..."
Compared favorably to Base 10 and CoreWeave; Base 10 had low-profit contracts with Cursor and poor capital efficiency
What creators say
"I'm a big fan of Fireworks and we are using them quite a bit. Yes, we like them a lot. I also tried to convince them to make their software available on prem right now."
More from Daniel Dines →"I inference on Fireworks, which is a really nice service where you can just pay by the token, and if you're using these open weight models, they're not that expensive by token. So that's a great way to do that."
